[Leica] Noctilux and Back Focus Adjustment

[robert.rose at mac.com (Robert Rose)]

Using a 2mm hex wrench I was able to adjust the focus on the M8 and  
now the Noctilux is useable.  It made an enormous improvement.

My other lenses seem to be fine at the new setting, with the  
exception of a 50 mm Summicron.

In any event, the Noctilux seems to be dead on now, and I have  
previously not used it (even with my M6 and M7) because I could never  
seem to focus it.   So I am going to shoot with this "new lens".

For the faint of heart, I assure you that it is very easy.  You just  
insert the wrench into the roller, and twist gently a few degrees.  I  
went about 5 deg. toward the red dot.  I can send pictures if anyone  
is interested.

Cheers,
